On all motorcycles about 80%, yes 80 percent of the stopping "power" is the front brake,the only thing watch out not to slide the front tire in lose debries.
between 60 - 75%. Depends on how much weight is biased toward the front wheel and how much brake pressure is applied.
65% - 75%
65 to 70 % depending on the type of pad material (late models only) Frt brakes are for stopping, rear brakes are for slowing.
The most effective brake is the front brake.

When stopping you should always use both your front and rear brakes. Aproximately 70 percent of the stopping power is in the front brake, and 30 percent in the rear.

YOUR FRONT ROTORS ARE WARPED. YOU NEED A BRAKE JOB.
More than likely a front or rear brake rotor is out of round. Depending on what model and year vehicle it could be a brake drum out of round also.
The front brakes on any vehicle do most of the stopping. When you apply the brakes the weight shifts to the front of the vehicle. For this reason the front brakes are needed more than the rear. Try stopping a vehicle with just the hand brake which applies only the rear brakes.

If you are going over 10 mph it can start to get very dangerous because most of the stopping force applied to a motorcycle is from the front brake (estimated 70%). The back brake can lock up easily.
